Role Context Error Causes Flows to be not installed (Li Plugin)

Tested the Legacy Netvirt in stable/Boron

a. 3node ODL feature: odl-ovsdd-openstack

openflowplugin features:

b. Used 3 Openstack nodes

c. After stacking successfully, checked the flow entires in all openstack nodes

expectation: initial pipeline flows to be installed

REsult: In 2nodes, the flows were installed successfully, it failed in 1 openstack node.

Checked the karaf .log and saw the below ERROR getting repeated for a long time

---------------END---------------

After sometime some flow entries were installed, but stil lthe initial pipeline flows were missing.

Attached the logs from all three ODL

Error is found in ODL3 log and once in ODL1 log.
